The City has a program which may be a good source of funding to cover some or all of the remaining repair work on Northwestern and future properties. It looks like the main eligibility requirement is just to have lived at the house for at least 6 months.
The Detroit 0% Home Repair Loans Program offers 0% interest loans from $5,000 to $25,000 to help Detroit homeowners invest in and repair their homes.
